いや段差等が生じ、意匠上の配慮に欠けていた。The above-mentioned prior art has not considered the following points. (1) Generally, the end piece is made of synthetic resin, and
Most of the door outer plates are made of thin steel plates, but the end faces are approximately 10 mm long in order to ensure a sufficient fitting margin to prevent rust and to prevent the end parts from coming off during foaming. Need to be covered. Therefore, as in the above-mentioned conventional example, the end piece is fitted to the door outer plate having the rising portion and the flange portion on both sides of the thin steel plate from the left or right direction or the vertical direction where the flange of the door outer plate is not formed and the stopper is fitted. With a structure that is worn as a door, when the door is closed and the refrigerator is viewed from the front, a fitting edge of a synthetic resin end piece appears at the end of the door surface made of thin steel plate, so the door surface There was a difference in gloss and steps, and the design was lacking in consideration.

があった。(2) In the case of a refrigerator in which a plurality of doors are arranged,
It is desirable in terms of design that the gaps between the doors are parallel and as narrow as possible in terms of expressing the sense of unity of the doors. However, in the door body in which the end pieces are arranged above and below the door outer plate as in the above-mentioned conventional technique, the direction in which the foaming pressure is applied when the foam heat insulating material is filled,
Since the fitting direction of the end piece and the door outer plate is the same direction, the end piece is pushed and moved by the foaming pressure, and there is variation in the fitting depth between the door outer plate and the upper and lower end pieces. As a result, variations in the height of the doors, inclination of the end piece fitting, and the like occur, making it difficult to keep the gaps between the doors parallel and as narrow as possible. Therefore, as a result, there has been a problem that the gap between the doors has to be large with a margin.

ど問題にならない。However, in this embodiment, since the flange portion 2a of the outer panel of the door is fitted in the engaging groove 4a of the end piece 4, the movement thereof is suppressed by the rigidity of the flange portion 2a. Also, the bulge of the end piece itself can be suppressed by the ribs 4b on the back surface of the end piece and the reinforcing iron plate 4c. Therefore, the H dimension is determined by the dimension of the door outer plate 2 without being significantly affected by the dimensional tolerance of the foaming hood 8.
This makes it possible to obtain a door with higher dimensional accuracy than conventional doors. Since the depth dimension D of the heat insulating door 1 is smaller than the height dimension H, the variation in the dimensional tolerance is small, so that the door body is not so problematic.
